Had to ask all the gurus who use tally, can u import the data into another database. ie.mysql, sql, oracle, (I know i'm going to get abuses for next two) access, sql. If the answer is no have you ever thought what are we all going to do if tally tomorrow closes shop? Think about it.
As far as Tally 6.3 goes no i've not suceeded in doing this one even through wine. But I have seen a pirated version of tally 5.* work on wine, u will have to change the path in tally.ini file as to where the data is beeing stored (search the archives it's discussed before).
Tally claims that 7.2 has a linux version (with rpms for redhat) I've written to them for a demo (No luck).
